Until now three-dimensional geometry was difficult to teach – the complexity of designs in perspective, models that are difficult and time-consuming to construct ... Cabri 3D is the only program that enables you to alleviate these construction difficulties and that also contains the benefits of interactive geometry.
How can you use it?
You can create activities that facilitate the introduction and understanding of new concepts, promote the discovery of theorems, instead of just showing them and help model real-life situations.
Generate classroom resources by inserting text or pictures in a figure, modifying graphical elements, copying/pasting into other software and producing high-quality printouts.
Present activities to students, have them manipulate figures, observe and guide them. Using Cabri allows you to better assess individual student comprehension.
Expand online by integrating figures that can be manipulated on web pages or by incorporating Microsoft Office documents.
Have students solve problems directly linked to the NCTM standards with possible interdisciplinary connections to physics, geography and the arts.
Basic constructions with planes, spheres and lines.
Study of common solids: with a click of the mouse, the student or teacher can construct pyramids, parallelograms, cylinders and cones.
Sections of solids: The user can represent and determine planar sections of convex polygons.
Measurements and calculations: Find measurements related to objects - distances, lengths, area, volumes and angles, and use them in calculations.
Through tools that facilitate visualization, students and teachers can adjust viewing angles turning around the scene and appreciate the rendering of depth of the scene.
Different representations and perspectives of the same figure: the three angles of technical design, various perspectives.
Why would you use it?
Students can manipulate virtual models on a screen instead of having to rely on a physical model (which the teacher may or may not have in the classroom)
PRO: "Refresh the construction" tool replays the user's construction in case you forgot the sequence of clicks that brought you to your object.
PRO: Objects created can be printed.
PRO: Unfolding polyhedron into nets: Cabri 3D unfolds all polyhedron into nets, which are printable and can be reproduced onto card stock.
PRO: Animation tools: Particularly stimulating for students, the tools enable them to simultaneously put several elements of a construction in motion. It is ideal for modeling physical phenomena.
PRO: Especially amazing when used in conjunction with the SMART Board.
PRO: Has a gallery of pre-designed items ready to go.
CON: Students will lack the interaction and physical touch they miss with real objects.
CON: Price - $119 for a single user, $449 for ten users, $899 for a site license and this would be a great tool in a computer lab.
CON: User-friendliness. I have seen it demo-ed before and looks amazing. Constructing objects yourself is a bit frustrating - I have tried. And I feel it needs intense work in its user-friendliness.
